Sanic is a simple, small, express-ish HTTP framework built in C with libuv.
Originally, I built sanic with clang blocks in mind. So they're supported out of the box.
#include <gc.h>
#include <sanic.h>
sanic_init();
sanic_log_level = LEVEL_DEBUG;
sanic_http_on_get("/", ^void(struct sanic_http_request *req) {
res->response_body = "<h1>Hello, World!</h1>";
});
sanic_http_on_get("/people/{:name}", ^void(struct sanic_http_request *req) {
char *name = sanic_path_params_get(req, "name");
//sanic integrates with the Boehm GC to automatically deallocate returned data
res->response_body = GC_MALLOC_ATOMIC(18 + strlen(name));
sprintf(res->response_body, "<h1>Hello, %s!</h1>", name);
});
return sanic_http_serve(8080);A less elegant solution is to just pass handler functions as callbacks. With gcc, this can be done in a lambda-ish way, although I haven't found out how to make cmake understand that.
sanic_init();
sanic_log_level = LEVEL_INFO;
sanic_http_on_get("/", handle_index);
sanic_http_on_get("/people/{:name}", handle_get_person);
return sanic_http_serve(8080);sanic supports middlewares out of the box. These can either act as filters or as blockers for any request.
sanic_use_middleware(^enum sanic_middleware_action(struct sanic_http_request *req, struct sanic_http_response *res) {
if (strcmp(req->path, "/foobar") == 0) {
res->status = 300;
return ACTION_STOP;
}
return ACTION_PASS;
});
